最大实体原则在机械设计中的应用

On the application of the principle of the maximum substance in the machinery design

在机械设计中能否正确使用最大实体原则,关系到能否最大限度地降低生产成本,提高经济效益。分析最大实体原则的根据、检测方法和应用场合,有利于工程技术人员在工程设计中正确选用公差原则,有利于机械产品的最优化设计。

Whether the principle of the maximum substance can be correctly used or not in the machinery design is related to whether the cost of product can be cut down and the economic benefit can be increased to greatest extent . The analysis of the foundation, the inspecting method and the applied situation of the principle can help the engineers and the technicians to select the principle of tolerance correctly in engineering designs and be useful to the best design.
